The production of doubled haploids has become a necessary tool in advanced plant breeding institutes and commercial companies for breeding many crop species. However, the development of new, more efficient and cheaper large scale production protocols has meant that doubled haploids are also recently being applied in less advanced breeding programmes. This Manual was prepared to stimulate the wider use of this technology for speeding and opening up new breeding possibilities for many crops including some woody tree species. Since the construction of genetic maps using molecular markers requires the development of segregating doubled haploid populations in numerous crop species, we hope that this Manual will also help molecular biologists in establishing such mapping populations. For many years, both the Food and Agriculture Organization of the United Nations (FAO) and the International Atomic Energy Agency (IAEA) have supported and coordinated research that focuses on development of more efficient doubled haploid production methods and their applications in breeding of new varieties and basic research through their Plant Breeding and Genetics Section of the Joint F AO/IAEA Division of Nuclear Techniques in Food and Agriculture. The first F AO/IAEA scientific network (Coordinated Research Programme - CRP) dealing with doubled haploids was initiated by the Plant Breeding and Genetics Section in 1986.
Readers who loved Lola at the Library, Lola Loves Stories, and Lola Reads to Leo are in for a backyard treat. After Lola reads a book of garden poems, she wants to plant some flowers. She gets books from the library and chooses her plants. Then Lola and her mommy buy the seeds, make the garden, and mark the rows. Now it's time to wait. . . .
Containing an extensive range of photographs and authored by leading horticultural experts,Diseases of Temperate Horticultural Plants is an indispensable reference work for horticultural professionals, academics, students, crop producers as well as amateur horticulturists. The diseases of major crops are presented according to their classification, and the symptoms of each disease, causal pathogen and control measures for each condition are described.
